Using

1. Create

    var provider = window.localStorage;
    var offTasks = new OfflineTasks({
        provider: provider,
        connectionTest: function (callback) {
            //some connection test Function
            callback(null, 'error'); //or other status
        },
        timeout: 10000, //check the connection timeout
        autorun: false  //to run the task immediately after saving

        //something do there
        callback('error'); //or other status
    });

3. Add tasks

    var task1 = {data: 'example 1'};
    var task2 = {data: 'example 2'};
    offTasks.save('taskName', task1);
    offTasks.save('taskName', task2);
    // in the storage will be saved [{data: 'example 1'}, {data: 'example 2'}]

or

    var tasks = {
        taskname1: {data: 'example 1'},
        taskname2: {data: 'example 2'}
    };
    offTasks.save(tasks); // in the storage will be saved 2 different task

    var task1 = {data: 'example 1'};
    var task2 = {data: 'example 2'};
    offTasks.save('taskName', task1);
    offTasks.save('taskName', task2, true); // rewrite tasks is true
    // in the storage will be saved [{data: 'example 2'}]

or

    var tasks = {

    };
    var tasks2 = {
        taskname1: {data: 'example 3'},
        taskname2: {data: 'example 4'}
    };
    offTasks.save(tasks);
    offTasks.save(tasks, true); //in storage will saved {data: 'example 3'} and {data: 'example 4'}

4. Load all tasks from provider

    var tasks = offTasks.load();

5. Load tasks by keys from provider

    var keys = ['key1', 'key2'];
    var tasks = offTasks.load(keys);

6. Run tasks

    // all tasks
    offTasks.run();
    // tasks by keys
    offTasks.run(keys);

7. Remove task

    offTasks.remove('key');
